2. You can not forced to work without meet the prescribed working
conditions.

3. During lifting, mast and platform can not collide with any
obstacles.

4. The ground personnel can't control device without the
instruction of altitude operations personnel.

5. After the platform raised, it is prohibited to stand or stacked
items below it.

6. Prohibit to changes, modifications and waste safety devices.

7. Prohibit overloading rise.

8. Prohibit moving the charging machine.

6. Advantage

Simple ,safe , convenient are the basic requirements for the
customer of small aerial work platform . simple vertical mast lifts
are applied hydraulic and chain mechanism for lifting,and the
structure is simple buy durable , with tiny size and light weight ,
GTWDY series has been widely used in hotel ,restaurant and shopping
mall for maintenance service .

The double-ladder rotation-prevention sleeve-cylinder type
hydraulic lift is the ideal equipment of the single-person high
altitude working with the height from 16 meters to 32 meters, which
has the advantages of being strong in safety, high in stability and
easy to operate. The main body of the product is the multi-level
telescopic hydraulic oil cylinder, which is made of the cold-drawn
pipe with the high intensity. The two points different from the
single-ladder rotation-prevention sleeve-cylinder type hydraulic
lift are that the double-ladder sleeve-cylinder type hydraulic lift
is equipped with two hydraulic pump station, which can realize the
ascent with the double-speed and adjust the speed of the descent.
The double-ladder rotation-prevention sleeve-cylinder type lift is
equipped with two sets of the rotation-prevention ladder so that
the rotation of the table surface can be effectively prevented when
the working staff operate on the high altitude. The safety
performance and the stability of the double-ladder
rotation-prevention sleeve-cylinder type lift are better than that
of the single-ladder rotation-prevention sleeve-cylinder type
hydraulic lift.
